The demand for corn in Indonesia is dominated as raw material for animal feed, so the high and low price of corn will have a big impact on the price of livestock products such as chicken and chicken eggs. The Covid-19 gives an impact on the uncertainty of food commodity prices. As we know, food price stability is one of the supports for maintaining a balance of production and consumer buying power. This study aims to analyze the price volatility of corn, chicken meat, and chicken eggs in Indonesia during the Covid-19 pandemic. The ARCH/GARCH model was used as an approach to analyzing volatility in the monthly prices of corn, chicken meat, and chicken eggs at the consumer level during the January 2011-June 2020 period. This research showed that the price of corn and chicken is categorized as high volatility category, while chicken eggs are a low volatility category with the form is asymmetric. It can be concluded that the price uncertainty faced by consumers in the future for corn and chicken meat will be bigger, while chicken eggs will be decreased. Therefore, it is expected that the government will make policies for maintaining the stability of food supply and prices.

With the agility of supply chain, competitive advantage can be maintained by business people by responding to environmental changes quickly and facing uncertainty. This research investigates the impact of supplier innovation on supply chain agility with information sharing and strategic resource as a mediator. At the same time testing the effect of information sharing and strategic sourcing on supply chain agility. The research sample used 65 coffee shops which were obtained from the response of the owner or manager of the coffee shop in Malang Area, known as the city of a million coffee shops. The rapid development of coffee shops in Malang Area demanding coffee businesses to respond quickly to changing consumer trends by maintaining the supply of coffee beans from the highest quality suppliers. This study was analyzed using structural equation modelling methods. The results revealed that supplier innovation significantly influences information sharing, strategic resources and supply chain agility. In addition, information sharing and strategic resources have a strong influence on supply chain agility. Thus, managers and or coffee shop owners need to establish good and sustainable relationships, especially to deal with changes in the business environment.

COVID-19's negative externalities disrupted the supply of several commodities. Meanwhile, to combat the spread of COVID-19, various countries have implemented a lockdown policy, which impacts the economy's balance. Consumers' risks are increasing due to economic changes caused by the COVID-19 pandemic, which affects the higher level of volatility of various agricultural commodities in Indonesia, particularly strategic commodities. Thus, this research was designed to examine the experience shock of strategic food consumers during Covid-19 pandemic. The ARCH/GARCH model was used to describe the strategic food price movement pattern using a set of weekly consumer price data from March 2020 until August 2021. This study found price volatility of strategic food commodities is classified into three categories. For starters, the extreme volatility of commodities such as garlic and cayenne pepper indicates that future buyers will face more significant uncertainty and risk. Furthermore, these commodities will generate fluctuating price swings in the future, resulting in greater experience shock for consumers. Second, commodities with high price volatility, such as rice, chicken meat, eggs, shallots, and sugar, signal that these commodities will subject consumers to a huge shock due to their high price volatility. Third, minimal volatility, such as that found in meat, red chilli, and cooking oil, indicates that customers will face less uncertainty in the future.

The increase of unsustainable human activities in watershed areas gave a huge pressure, causing land degradation and reduced the river water quality. This study aimed to describe the land use management and calculate the carrying capacity as a part of natural resource management of Bangsri Micro Watershed, the upper Brantas watershed in East Java, Indonesia. Data was gathered from five villages through interviews, questionnaires, and focus group discussions with multiple stakeholders. In addition, data from the local government statistics bureau (i.e., Statistics Indonesia) was also used. From the total 2,765 ha land area, eight different land use were identified with agroforestry (970 ha) being the largest and bare land (43 ha) being the smallest. There were 17 crop patterns with 10 different commodities recorded. Based on the present land use, the total land monetary value (biocapacity) was 298 billion Indonesian Rupiah (IDR) or equal to 27,278 tonnes of rice production. From the total population of 27,645; the total annual income (i.e., ecological footprint based on the minimum wage and real household income) needed is 577-854 billion IDR (72,101-106,771 tonnes of rice), thus considered as a deficit carrying capacity value. An urgent watershed management planning is needed to reduce the environmental pressure while ensuring the fulfilment needs of the people in Bangsri Micro Watershed.

The consumption patterns of Indonesian households are around 85% derived from vegetable proteins and 15% from animal proteins. Furthermore, low-income households often find it challenging to fulfill their energy and protein needs. It is becoming a severe issue when the Covid-19 break in Indonesia and puts many essential animal protein commodities into an excellent uncertainty condition. Although it is accepted that the effectiveness of population growth, none have assessed the relationship with the price volatility that was formed by the Covid-19 issue. This research aims to develop an econometric model on essential animal food demand and how their price volatility trend during Covid-19. The Linear Expenditure System (LES) was chosen as an approach to describing the demand for food commodities from essential animal protein sources using SUSENAS data for the 2019 enumeration period, while the ARCH/GARCH model was used as an approach to describe the pattern of price volatility using set of consumer price data from January 2010 until August 2020 enumeration period. This research shows that the price elasticity of the essential animal protein sources of food commodities shows that all commodities are inelastic. At the same time, changes in the relationship between essential animal food commodities reflect an overall shift in the consumption of society towards essential animal food commodities themselves. On the other hand, there is a specific movement in price volatility toward an explosive term, which led to a great uncertainty that will face both of consumers and producers in the future.

The increasing number of consumers’ purchase intention on green products can be seen through the rising number of individuals who are willing to pay more for these products, and it proves this problem has attracted the attention of many circles. This article aims to examine what factors can influence the growth of student purchase intention on green products. The expansion of the Theory of Planned Behaviour was carried out to include two factors that are expected to influence student purchase intention, namely environmental knowledge and self-transcendence. Cluster random sampling is used to select samples that previously have been calculated using the Taro Yamane formula and the Parel formula with a total sample size of 136 samples. The results processed with the SEM-PLS (Structural Equation Model - Partial Least Square) showed that environmental knowledge was found to be unable to influence student purchase intention on green products, this is supported by the statement that high knowledge is not always in line with attitudes and practices generated. Self-transcendence was found to affect the growth of student purchase intention in green products, and this can happen because self-transcendence can affect the formation of consumer purchase intention.
